+# DiscoPoP Explorer
+## Executable
+`discopop_explorer`
+
+## Purpose
+Analyze the [output of the instrumentation and profiling stage](../data/Profiling_and_instrumentation_output.md) in order to identify opportunities for parallelism in the sequential target code ([parallel patterns](../data/Parallel_patterns.md)).
+As part of the analysis, the [program execution graph](../data/Program_execution_graph.md) is created.
+
+## Required input
+- [Filemapping](../data/Filemapping.md)
+- [Profiling and instrumentation output](../data/Profiling_and_instrumentation_output.md)
+
+## Output
+Identified [parallel patterns](../data/Parallel_patterns.md) are stored in a file named `.discopop/explorer/patterns.json` by default. This information can be imported by various other tools in the framework.
+
+## Note
+For a more detailed description of the available run-time arguments, please refer to the help string of the respective tool.
